The Lowdown
Right then, let’s have a look at what Jaconé has got cookin’ for us over the next couple of weeks. We’re in for a proper mixed bag here, with some real standout sessions if you time it right, but also some days where you might as well stay on the beach with a cold one.
The water is sittin’ around 73°, which is pretty much what you’d expect for this time of year – nothing unusual there.
We kick things off proper on Monday the 24th of August with a solid pulse of south swell. The morning’s got 8ft of south swell, period a clean 13 seconds, and that cross-off breeze from the ESE is gonna keep things tidy. The combined energy is strong at 1935, so there’s plenty of push. This is excellent gear for experienced surfers only – beginners, give this one a miss, it’s a bit too much. The standout, without a doubt, is Wednesday morning the 26th. We’ve got 5ft of south swell, a lovely 16-second period, and the wind goes glassy from the WNW. That is a magic window. The energy is still strong at 1943, but that clean, glassy surface will make it feel like silk. This is the pick of the whole run for the experienced crew.
Tuesday the 25th holds decent 8ft south swell in the morning with cross-off wind, but it’s a step down in quality. Wednesday afternoon sees the swell jump back up to 8ft with a 15-second period, but the cross-off wind won't be as clean as that glassy morning. Thursday the 27th is another cracking morning: 8ft of south swell, 14 seconds, and glassy conditions again from the NW – another top-tier session. Thursday afternoon has a nice offshore from the ENE, still with 7ft of clean south swell.
Into Friday the 28th, the swell drops to 4ft in the morning with light offshore from the NE – clean but smaller. After that, it fades and the quality drops. Saturday the 29th is small on a new ENE swell, and by Sunday the 30th we’ve got some poor, choppy conditions from a cross-onshore wind. That’s a few days of looking average.
Then there’s a bit of a surprise. Monday the 31st of August is a beauty – 7ft of ENE swell, 9-second period, and the wind goes dead calm, glassy in the afternoon. Combined energy at 762, but that glassy surface makes it special. Tuesday the 1st of September is a write-off – poor conditions and onshore wind.
We get a bit of a comeback mid-week. Wednesday the 2nd of September sees 7ft of SSW swell, 10-second period, with clean cross-off winds. And then Thursday the 3rd of September morning is another standout: 7ft of south swell, 12-second period, and a gentle offshore from the NE. The combined energy is 1116 – strong – and it’ll be clean and lined up.
After that, from Friday the 4th into the second week, the swell drops away and the winds get stronger and more onshore. By Saturday the 5th and Sunday the 6th, it’s small and messy, then Monday the 7th has a brief spike of 4ft south swell with a good period (11 seconds) and offshore wind, but it’s short-lived before Tuesday the 8th turns into a complete dud with onshore winds again.
So the bold standouts are Wednesday morning the 26th and Thursday morning the 27th for that glassy south swell, and Monday the 31st of August for the glassy ENE swell. Thursday the 3rd of September morning is also a top pick.
Alright, that’s the picture from here. Stay sharp and pick your windows.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
